What’s the Difference Between Collagen Peptides and Hydrolyzed Collagen?

If you’re new to collagen supplements and looking into the various options on the market, you may see some terms that are unfamiliar to you, such as hydrolyzed collagen, collagen peptides, and collagen hydrolysate. Without a proper explanation, these words may be meaningless to you, but they are important to know about if you are considering a collagen supplementation regimen, as they will help with choosing a collagen supplement that meets your needs and gives you the maximum benefits possible.

So what’s the difference between collagen peptides and hydrolyzed collagen? Is there one? Read on to find out. 

The Difference Between Hydrolyzed Collagen and Collagen Peptides

First things first: there is no difference between hydrolyzed collagen and collagen peptides. They are two different terms for the same thing. Collagen hydrolysate ^[1] is another synonym for this product. This means that you may see any of these terms used on packaging for collagen supplements and receive the product you’re looking for. 

However, collagen peptides are different from the collagen found in our bodies. Indeed, our bodies naturally produce collagen, which provides structure, strength, and lubrication throughout the body, supporting the health of our skin, hair, nails, joints, bones, and more. However, over time, our bodies’ natural collagen synthesis begins to decline, leading to visible signs of aging (such as fine lines and wrinkles) as well as joint discomfort and other unpleasant symptoms. By taking collagen supplements, we are not only replenishing our bodies’ supply of collagen artificially, but prompting the body’s production of collagen to increase as well. 

If you’re seeking to restore your body’s natural collagen production, the best collagen supplements you can use are collagen peptides. This is a type of collagen that has undergone a process called enzymatic hydrolysis, which uses particular enzymes to break down collagen molecules into shorter chains of amino acids. The result? An end product with a higher bioavailability than traditional forms of collagen, making it more easily absorbed into the bloodstream, in turn yielding better results. 

Collagen Peptides vs. Traditional Collagen

As noted above, the big difference between collagen peptides and traditional forms of collagen is its effectiveness in the body. Because collagen peptides are easier for the body to absorb, they provide greater benefits. Does this mean traditional collagen is ineffective? Not entirely – it can certainly provide some of the same rewards as collagen peptides, but a lower absorption rate will mean you get reduced benefits from what you will find in collagen peptides. 

Natural Sources of Collagen

In addition to being naturally synthesized by our bodies, collagen also can be found in some foods. This can also be a way to restore collagen levels, though it can be difficult to do so with the same consistency as taking collagen supplements, as these foods are generally not consumed daily. These foods also do not contain collagen peptides, meaning they will not offer as direct absorption as supplement products. 

Collagen can be found in the following foods:

What is a protein?

Collagen [2] is a structural protein in the body that makes up a significant component of our connective tissues, such as skin, tendons, ligaments, and bones. It provides strength, support, and elasticity to these tissues, contributing to their overall integrity and functionality. Collagen protein is the most abundant protein in the body, though there are different types of it, impacting and benefitting different parts of the body. This is why it is important to do your research on what type of collagen appears in your collagen powder, pill, or gummy. (For more information about choosing the best supplement for you, read on.) 

What are amino acids?

Amino acids are the building blocks of proteins [3], and collagen, being a protein, is composed of specific amino acids. In the case of collagen, the primary amino acids are glycine, proline, hydroxyproline, and arginine. These amino acids play a crucial role in forming the unique triple-helix structure of collagen, contributing to its strength and stability. The presence of these amino acids is essential for collagen’s function.

Choosing the Right Collagen Supplement for You

When deciding which supplement you’d like to incorporate into your diet, it’s important to take your particular needs, goals, and dietary habits into consideration. 

First and foremost, it’s important to know your source of collagen when you make your selection. Collagen peptides can be derived from various sources, including bovine (cows), porcine (pigs), marine (fish), or plant-based alternatives. If you are vegan or vegetarian, or if you have other dietary restrictions, it’s important to know this before you choose your supplement type. 

It’s also imperative to make note of which collagen peptide type is found in your product. Type I collagen is abundant in skin, bones, and tendons, while type II is found in cartilage and joint tissue. Your product of choice should specify which type it contains. It’s often beneficial to choose a supplement that provides a combination of types for comprehensive health benefits. 

Benefits of Collagen Peptides

The different forms of collagen found in our bodies have different benefits, and different collagen peptide supplements can target each of these areas to restore our youth, mobility, and overall health.

Collagen is perhaps best known for its skin benefits. Collagen provides skin with its structure, contributing to its elasticity and strength. By incorporating collagen peptides into your routine, studies have shown ^[4] individuals can improve their skin hydration, firmness, and overall elasticity. This can contribute to a more youthful appearance and potentially mitigate the most visible signs of aging, such as fine lines and wrinkles.

In addition to skin benefits, collagen peptides play a crucial role in supporting the health of hair and nails.
Collagen is an integral part of the hair follicles as well as the structure of nails. By taking daily supplements, individuals may observe stronger, healthier hair and nails, with reduced brittleness and breakage. Those who are suffering from hair loss or weak nails can take collagen peptide supplements to see demonstrable improvements. 

Collagen peptides also offer advantages for joint health. As a major component of cartilage, collagen contributes to the structure and flexibility of joints. Regular supplement use has been linked ^[5] with reduced joint pain and increased joint mobility. This makes it a valuable supplement for individuals looking to support joint function and alleviate discomfort associated with conditions like osteoarthritis.

Beyond the benefits for skin, hair, and joints, collagen peptides can have positive effects on other areas of the body. Collagen is present in various tissues, including tendons, ligaments, and bones, contributing to their strength. Taking collagen peptides may aid in maintaining healthy bone density as well. Additionally, collagen is increasingly found to be crucial for gut health ^[6], as it helps in the formation of the intestinal lining, potentially promoting digestive wellness. This promises to be one of the most exciting new frontiers of collagen in wellness.
